Answer
Graph for $y=-f\left( x \right)$ can be found by reflecting the graph of $y=f\left( x \right)$ about the $x-axis$.
Work Step by Step
The values of the function are the values of y obtained corresponding to every x. If the value of y obtained is multiplied by a negative sign, then this will invert the graph about the x axis. Thus, the inverted graph will be obtained.
